This chapter provides a checklist to help you classify your hazardous waste and your
nonhazardous industrial waste. For an overview of these types of waste, refer back to Figure 1in Chapter 1; for more details, refer to 30 TAC Chapter 335 Subchapter R Sections 335.501–508. (You can obtain your own copy of state rules from the TCEQ publications unit; ways tocontact this unit are listed under the heading “TCEQ and EPA Forms” in Chapter 6.)
Process Knowledge vs. Analytical Testing In determining a waste stream’s classification, a generator may use process knowledge
and/or analytical testing. Process knowledge is the owner or operator’s knowledge about howthe facility operates, how a waste was produced and handled, and other information based onoperating experience. Analytical testing is information about a waste from laboratory analysis.
In the checklist, the nonhazardous classification criteria that could involve analytical
testing have been marked with an *. This marking does not mean that analytical testing is the only way to evaluate these criteria. If sufficient process knowledge is available, little or no analysis may need to be performed. You should evaluate whether you have enough process knowledge about the waste to classify it or whether analytical testing is needed. Documentation Regardless of whether you rely on process knowledge or opt for analytical testing, you
must fully document the information used in making your waste classification. A completed checklist does not qualify as full documentation. Documentation should be in a written and/ or electronically stored format that is reasonably accessible and easily reproducible. For details on documentation requirements, see Chapter 4. Part I. Hazardous Waste Determination
All waste generators should work through Part I of this checklist. In this part you will
determine whether your waste is hazardous because (a) it is listed as hazardous by EPA or (b)it displays characteristics that EPA says make it hazardous.
In federal regulatory language, the first step in classifying your waste is called “making
a hazardous waste determination.” The definition of hazardous waste, based upon theResource Conservation and Recovery Act (RCRA), is found in Title 40 of the Code of FederalRegulations (CFR), Part 261.
This TCEQ guidance document reflects the hazardous waste definition in the FederalRegister as of July 1, 2004. If that definition changes, the generator is still responsible formaking an accurate hazardous waste determination in accordance with the latest regulations—instead of with what is printed in this guidance document.
the answer to any of the questions in Part I is “Yes,”
Possible Exclusions from Hazardous Classification Under certain conditions, some types of wastes are excluded from being considered
hazardous (40 CFR Sections 261.3–4). Generators may wish to review these exclusions beforeworking through Part I of this checklist. Part I-A. Listed Hazardous Waste Determination
The EPA lists some 400 hazardous wastes. Information to Help You Make This Determination
Descriptions of listed waste are found in 40 CFR Part 261, Subpart D, Sections 261.31–33.
These wastes are often referred to as follows:
■ “F” listed waste (waste from nonspecific sources, Section 261.31);
■ “K” listed waste (wastes from specific sources, Section 261.32);
■ “P” listed waste (unused acutely hazardous off-specification materials as well as
container residues and spill residues of these materials, Section 261.33);
■ “U” listed waste (unused toxic hazardous off-specification materials as well as
container residues and spill residues of these materials, Section 261.33). QUESTION: Is the waste a listed hazardous waste, or is it mixed with or derived from one? Part I-B. Characteristic Hazardous Waste Determination
Wastes may be hazardous if they display any of four characteristics: ignitability,
corrosiveness, reactivity, or toxicity. Information to Help You Make This Determination Ignitability Wastes that are hazardous because they may ignite include the following:
■ Liquid wastes (other than those aqueous waste containing less than 24 percent alcohol
by volume) that have a flash point less than 60OC (140OF). (The test method is thePensky-Martens closed cup tester, using the test method specified in ASTM StandardD-93-79 or D-93-80, or a Setaflash closed cup tester, using the test method specified inASTM Standard D-3278-78.)
■ Nonliquid wastes that, under standard temperature and pressure, are capable of causing
fire through friction, absorption of moisture, or spontaneous chemical changes and,when ignited, burn so vigorously and persistently that they create a hazard.
■ Wastes that meet the definition of an ignitable compressed gas (see 49 CFR Section
■ Wastes that meet the definition of an oxidizer (see 49 CFR Section 173.151). QUESTION: Is the waste ignitable according to 40 CFR Section 261.21? Corrosiveness Wastes that are hazardous because they are corrosive include the following:
■ aqueous wastes with a pH of 2 units or below or of 12.5 units or above;
■ liquid wastes that corrode steel at a rate greater than 6.35 mm (0.250 inches) per year. QUESTION: Is the waste corrosive according to 40 CFR Section 261.22? Reactivity A waste is considered reactive if it meets any of the following conditions:
■ It is capable of detonation or explosive decomposition or reaction
▼ at standard temperature and pressure,▼ if subjected to a strong ignition source, or▼ if heated under confinement.
▼ potentially explosive,▼ reacts violently, or▼ generates toxic gases or vapors.
■ If a cyanide or sulfide-bearing waste is exposed to pH conditions between 2 and 12.5,
it can generate enough toxic gases, vapors, or fumes to present a danger to human health or the environment. Generally, if a waste generates 250 ppm or more of reactive cyanides or 500 ppm or more of reactive sulfides, it is considered a reactive waste. (It should be noted that these levels of reactive compounds are just guidance. Each waste must be evaluated for reactivity on a case-by-case basis).
■ It is normally unstable and readily undergoes violent change without detonating.
■ It is a forbidden explosive (as defined in 49 CFR 173.51, or a Class A explosive as de-
■ It is a Class B explosive (see 49 CFR Section 173.88). QUESTION: Is the waste reactive according to 40 CFR Section 261.23? Toxicity A waste is toxic if the toxicity characteristic leaching procedure (TCLP) shows that a
representative sample from the waste contains one or more constituents at or above the levelslisted in Table 3-1. The TCLP is described in EPA Method 1311 (SW-846). QUESTION: Is the waste toxic according to 40 CFR Section 261.24? Table 3-1. TCLP Regulatory Levels

QUESTION: Is the waste a semi-solid or solid that, when mixed with an equivalent weight of ASTM Type II laboratory distilled or deionized water, produces a solution with a pH of 2 or less or 12.5 or more?
(Exception: for solidified, stabilized, encapsulated, or otherwise chemically bound wastes, an exception is provided in 30 TAC Section 335.505(3)) * QUESTION: Does the waste leach Class 1 toxic constituents at or above the levels listed in Table 1, Appendix 1 of 30 TAC Chapter 335 Subchapter R when submitted to the toxicity characteristic leaching procedure (TCLP)? *
(For a copy of Table 1, Appendix 1, see Appendix C of this guidance document.)
(Where matrix interferences of the waste cause the Practical Quantitation Limit (PQL) ofthe specific analysis to be greater than the Maximum Concentration listed in Table 1,Appendix 1 of 30 TAC Chapter 335 Subchapter R, then the achievable PQL becomes theMaximum Concentration, provided that the generator maintains documentation thatsatisfactorily demonstrates to the TCEQ that lower levels of quantitation of a sample arenot possible.)
A satisfactory demonstration includes the results from the analysis of the waste for thatspecific constituent by a laboratory using an appropriate method found in Test Methodsfor the Evaluation of Solid Waste, Physical/Chemical Methods (EPA SW-846); Methodsor Chemical Analysis of Water and Wastes (EPA-600 series); Standard Methods for theExamination of Water and Wastewater; American Society for Testing and Materials(ASTM) Standard Methods; or an equivalent method approved by the TCEQ.

THEN the nonhazardous industrial waste is a Class 3 waste. Part IV. Variance from Waste Classification
The TCEQ may determine, on a case-by-case basis, the merits of a variance request for a
specific nonhazardous classification. The burden of justifying the need for a variance is on therequestor. The requestor must submit information sufficient to clearly indicate the issuesinvolved, the reason(s) for the request, and both the positive and negative impacts that mayresult from the granting of the variance. (The regulations corresponding to these types ofvariance requests can be found in 30 TAC Section 335.514, Variance from WasteClassification Provisions.)
* As a reminder, these characteristics need not necessarily be addressed by analytical testing. A generator may be able to address them through process knowledge.

Applicability: Class 3 Waste Evaluations
This test is intended only for dry, solid wastes, i.e., waste materials without any free liquids.
1. Place a 250 gram (dry weight) representative sample of
the waste material in a 1500 milliliter Erlenmeyer flask.
2. Add 1 liter of deionized or distilled water into the flask and
mechanically stir the material at a low speed for five (5) minutes.
3. Stopper the flask and allow to stand for seven (7) days.
4. At the end of seven (7) days, filter the supernatant solution through
a 0.45 micron filter, collecting the supernatant into a separate flask.
5. Subject the filtered leachate to the appropriate analysis.
Form Codes(30 TAC Chapter 335 Subchapter R Appendix 3)
Applicability: All Waste
In determining a waste stream’s form code, it is recommended that the generator firstdetermine into which major category the waste stream fits (e.g. inorganic liquids). Thegenerator should then review all the form code descriptors in that category to determine whichcode or codes best describe the generator’s waste stream. The generator should then choose,from the narrowed-down list, a form code for the waste stream.
Form codes are fairly generic in their descriptions. It is possible that more than one form codemay be applicable to a particular waste stream. Generators should assign the form code whichbest describes the waste stream. If more than one form code can “best describe” the wastestream, then the generator should choose one of those several codes. Waste Description Waste Description Lab Packs

Benefits of Natural Hormones Conventional Hormone Replacement Therapy (HRT) for women usually consists of a standard prescription of hormones – most commonly Premarin and Provera. Premarin is derived from the urine of pregnant mares that are kept enclosed in tight spaces so that urine is easily captured. Provera is synthesized in the lab from natural progesterone, then modified for reason
